The current strategy being used to flag buttons as either default or cancel will not allow for a button to act as both ... but I agree with you, buttons that act as both would be usefull (like the close form thingy just mentioned).

Will have to do a little experimenting but based on some of the development work going on right now (building a new custom button) think there might be a way to do this - will give a go for next release.
